I have the new dryer, (mounted next to radiator in front), with the hoses
disconnected.  Hoses disconnected at compressor too. Think it's OK to pour
AC flush in the hoses that connect to the dryer and flush through with air?
Would that push the flush/solvent through both sides of the system without
damaging anything or leaving a bunch of solvent behind? I've been reading
up on it and finding a lot of suggestions for taking the whole system apart
and flushing the pieces individually.  I would love to avoid that if
possible.
